1. Great for Sound Boards
It's tiny, and it's FAST to setup. I'm a wedding videographer, and don't have time to spend forever on audio, so I use this to plug straight into the soundboard and leave. Takes like 5 seconds. I am using a 1/4" to 1/8mm cable, and I plug into the dj's headphones port -- I put this on auto-leveling and it works like a dream.
It records a little hot, so keep in mind that you might have slight peaking if your speaker begins talking really loud after it was silent for several seconds... But all to say, really solid, and handles dynamic range of voice really well. All audio from the pastor and the passage-reader in the above video was taken with it.
2. Not a recommended lav microphone
Awful form factor. Sure, it's small, but it's awkward because it's long and sticks out of most pockets. Uncomfortable when strapped to a belt. Furthermore, the microphone that comes in this pack is crappy.
LAV RECORDER RECOMMENDATION: A recorder that is lower profile, higher quality, AND CHEAPER is the Tascam DR-10L. I am also using it in the video above, so that is where the bride's audio is from.
3. On-Board Microphone is horrific:
The on-board microphone picks up your hands touching it, or even your blood pumping in your fingers. Super sensitive. However, the little tripod attachment in this pack helps with that. However, if you're outside, there is no wind protection, and the mic-guards resist cotton-ball treatments. I recommend something else.
OVERALL
This thing is GREAT at 2 things -- 1. Being tiny, 2. Taking a solid, high-quality feed
Other than that, I recommend other, more specialized products.
